ABSTRACT:
A liquid crystal projector has three liquid crystal panels for modulating first color light, second color light, and third color light respectively. A light synthetic device synthesizes each color light modulated by the liquid crystal panels. A projection lens projects the light synthesized by the light synthetic device. Setting members set the liquid crystal panels to the light synthetic device and wedge-type spacer members adjust the position of the liquid crystal panels in their planar direction and the direction perpendicular to the planar direction.insert-start id="INS-S-00001" date="20080805" ?The liquid crystal panels are secured to the light synthetic device through the setting members and spacer members.insert-end id="INS-S-00001" ?delete-start id="DEL-S-00001" date="20080805" ?The liquid crystal panels are secured to the light synthetic device through the setting members and spacer members.delete-end id="DEL-S-00001" ?
